PKR is being deliberately depreciated and target USD to PKR interbank rate is Rs. 125 which will realize in next few months or so, current rate is about Rs. 116
That's more than 5% reduction of all the assets you currently have in PKR.
So even if you decide not to buy USD, don't hold your wealth in PKR unless invested in business which returns can outweigh PKR depreciation, buy some other currency, any currency with good outlook.
